UNITED STATES PATENT OEEIoE.

JOHN H. IRWIN, OF PHILADELPHIA, PENNSYLVANIA.

LAMP-BURNER.

Specification forming part of Letters Patent No. 99,443, dated February1, 1870.

cone, of a perforated guide or support, which acts as a guide to placethe cone and shield in proper position and hold them there.

In the accompanying drawings, Figure 1 is a perspective view of myinvention; Fig. 2,

. same with cone and shield removed; Fig. 3,

vertical central section of Fig. 1 with the oilreservoir added.

This invention relates to an improvement in the construction of burnersdesigned to be used in connection with an air-chamber above the oil-pot;and it consists in constructing the burner with an outer imperforatejacket fitted at its lower end to engage with a collar on the top ofsaid air-chamber while the burner is fitted in the usual manner to asocket in the oil-pot, and the burner has therefore two supports.

It also consists in a mode of constructing the parts of the burner sothat the said jacket or shield shall act as a gage to insure the properrelative position of the wick-tube and cone; and it further consists inthe deflectingplate located at the top of the wick-tube.

That the construction and operation of this device may be fullyunderstood, I will particularly describe it.

G is an air-chamber located above the oilpot, and through this chamberthe air passes to reach the flame below the cone. Said ch amber G has acentral orifice, which encircles the socket in the oil-pot, and saidorifice is surrounded by the collar H, to receive the lower edge of thejacket of the burner, which thereby is supported not only in the oil-potsocket, but at the outer edge of the frame or jacket also, and istherefore more securely held in place than if supported by the socketonly. I

The perforated frame or casing B is fitted at its lower extremity to asocket in the top of the oil-pot, and at its upper edge it expandsoutwardly and joins the jacket A at a. The wick-tube O and the ordinarywick-riser are both attached to the frame B in the ordinary way, and thecone A rises above the wick-tube in the usual manner.

I I represent screws, or their equivalents, which may be attached tosecure the jacket A to the collar H, if it is thought to be necessary.

At the upper end of the wick-tube O, I attach a deflectingplate, D, bywhich the currents of air ascending from the air-chamber through theperforations in the frame B are turned away from the base of the flameand against the inner surface of the cone A, by which they are broughtback to the flame at a higher point, as indicated by the arrows.

As a process of manufacture, it is more convenient to form the jacket Aand cone A in one piece and separate from the frame B.

The shoulder a is fitted to the upper edge of the frame B, and, when theparts are in position, acts as a gage to cause the upper end of thewick-tube to come into proper position in reference to the slot F at thetop of the cone. This is made necessary because it is practically verydifficult to manufacture the oil-pot with the burner-socket locatedexactly in the center of the orifice surrounded by the collar H, andwithout an adjusting gage either the upper end of the wick-tube would beimproperly located in respect to the slot F, or the opening in the topof the air-chamber would be imperfectly closed.

Having now described my invention, what I claim as new is- 1. Alamp-burner provided with an outer imperforate jacket, A, fitted at itslower edge to engage with a collar, H, or its equivalent, to give theburner two supports, as set forth.

2. The jacket A and cone A, formed of one piece, with a shoulder, a, incombination with the perforated frame B, fitted to said shoulder for thepurpose of gaging the adjustment of the wick-tube, as set forth.

3. A burner with a jacket, A, cone A, and deflecting-plate D at the topof the wick-tube, all constructed and arranged substantially asdescribed.

4. A burner constructed with the jacket A and perforated frame B,substantially as described, in combination with the air-chamber G,provided with a collar, H, or equivalent,

as set forth.
